Is a bequest of only the *Raqabah* (manumission bond) without the *Makatab*'s wealth valid?

Primary text

By analogy with the previous issue, if a man bequeaths only the *Raqabah* of the *Makatab* without his wealth (*Mal al-Kitabah*), the bequest is invalid. However, the bequest of the *Raqabah* alone is valid if the testator bequeathed it to one man and the wealth to another man.
